Public Social Media such as Facebook, Google, and Twitter become the primary way to user involvement. However, there is still a privacy concern with these public Social Media services. Public Social Networks today have more power than any government. They can know everything about us, what we like, dislike, our secret conversation, how we feel, what we, and who we talk.
Link is a social network used to improve collaboration and communication between groups of people. It allows them to interact, socialize, share and consume information, thoughts, and ideas. In addition, it combines individuals into specific groups like a neighborhood subdivision. Link provides an opportunity for the community such as high school, universities, institutions, governments, non-government institution and others to engage. It also contains many features used to facilitate user interaction and collaboration. Some of these features include posting, comment on the post, real-time chat session, voting, user profile, and focusing groups.
